nolibc and __attribute__((__unused__))

["Paul E. McKenney" <paulmck@kernel.org>]

Hello!

My guess is that I should ignore the following checkpatch complaint on
the assumption that checkpatch doesn't realize that this is not built
as part of the Linux kernel.  But if my guess is incorrect, please let
me know, as it is a trivial change to make.

							Thanx, Paul
